    摘要: The double crucible for a glass drawing method has a heatable outer crucible (1) and an inner crucible (2) surrounded by the outer crucible (1), which is heatable separately from the outer crucible (1). Both crucibles (1,2) have an outlet nozzle (1a, 2a) for the glass to be drawn. To make glass fibers from heavy metal oxide glass (HMO-glass) with higher quality and comparatively simple crucible features, the outlet nozzle (1a) of the outer crucible (1) extends a certain distance beyond the outlet nozzle (2a) of the inner crucible (2). Surfaces of the outlet nozzles coming in contact with the glass melt are polished and are provided on a material, which has a reducing action on heavy metal glass in the melt in all cases. These surfaces also have sufficient mechanical strength for and chemical inertness to heavy metal oxide glass.

    摘要: A process for the remelting of glass bars, including the steps of introducing a glass bar into an upper end of a receiving shell; providing a molten bath having a surface underneath the receiving-shell; positioning the receiving shell such that a lower edge of the receiving shell is located at the height of the surface or above it; heating a lower end of the glass bar to a temperature above a softening temperature of the glass, resulting in a melt-off process at the lower end of the glass bar to produce a melt stream; controlling the melt-off process such that the melt stream continuously enters the molten bath proximate the surface with avoidance of a constriction; and drawing off melt from the molten bath by means of an arrangement for drop generation.

    摘要: The invention relates to novel uses of glass ceramics, wherein glass ceramics, in particular, in the form of a glass ceramic tube, are used. Said glass ceramics contain 0—less than 4 wt % P205 and 0 less than 8 wt-% CaO. The tubes can be used in multiple areas of application and/or in multiple types of lamps, for example in general lighting or car lights and in heat radiators, such as halogen lamps or incandescent lamps, and/or in high pressure discharge lamps or low pressure discharge lamps. The glass ceramics, can also, in particular, be minimised in order to form known backlighting in conjunction with background lighting of flat screens. Said type of glass ceramics have excellent spectral transmission in the visible wave length rang and are solarisation stable and absorb strong UV light.
